Artificial intelligence (AI) accurately predicts fall risk using gait analysis. Machine learning models identified individuals at higher risk, offering a streamlined approach to fall prevention strategies.

Area of Science:

  • Biomedical Engineering
  • Computer Science
  • Public Health

Background:

  • Falls are a significant global public health concern, necessitating early detection for effective prevention.
  • Traditional fall risk assessments are reliable but often resource-intensive and impractical for widespread use.

Purpose of the Study:

  • To evaluate the effectiveness of artificial intelligence (AI) in predicting fall risk using gait analysis.
  • To develop and validate machine learning models for early identification of individuals prone to falls.

Main Methods:

  • Gait analysis was performed using computer vision and machine learning on data from the Timed Up and Go (TUG) test and JHFRAT assessment.
  • Extracted gait features included stride time, step time, cadence, and stance time, analyzed separately for each foot and as averaged values.

  • Machine learning models, including LightGBM, were trained to distinguish between fallers and non-fallers.

    • Main Results:

    • The study achieved high accuracy in fall risk prediction, with the LightGBM model demonstrating 96% accuracy.
    • Both experimental setups (separate and averaged gait features) yielded promising results in identifying fall risk.
    • Simple machine learning models proved capable of identifying high fall risk individuals based on gait characteristics.

    Conclusions:

    • AI-powered gait analysis offers a promising, potentially streamlined method for fall risk assessment.
    • The findings highlight the potential of machine learning in enhancing public health strategies for fall prevention.
    • Limitations include dataset size and variation, underscoring the need for further research to improve generalizability.
